Question

Exponential functions have the form f(x)=b^x. What type of an exponential function would you have (increasing or decreasing) if the value of b is greater than one?

Answer 1

Answer:

Increasing

Step-by-step explanation:

Let's see what happens if we choose a value for b greater than 1.

Let's try b=2.

$f(x)=2^x$.

I'm going to keep increasing x. If y increases, the the function is increasing. If y decreases, the function is decreasing.

Let's start with x=1.

$y=2^1=2$

Now x=2.

$y=2^2=4$

The y's got higher as you increased x so the function is increasing.
